To @ZZ whom t may concern.-

Be itknown that I, WYATT GIBSON, a citizen of the United States,residing at Dodd, in the county of Fannin and State of Texas, haveinvented a new and useful Improvement in Churns, of which the followingis a specification.

The invention relates to improvements in churns.

The object of the present invention is to provide a simple andinexpensive churn, capable of quickly producing butter, and adapted totake up but a small amount of space, and capable of being readilyoperated.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claim hereto appended.

In the drawings-Figurel is a perspective view of a churn constructed inaccordance with this invention. Fig. 2 is a vertical sectional view.

Like numerals of reference indicate like parts in both the figures ofthe drawings.

l, 1, designate standards provided at their lower ends with feet 2, andconverging and meeting near their upper ends, and designed l to besecured to a floor orsupporting surface,

and braced by rods 3. The standards are connected near their lower endsby a horizontal bar 4, and have secured at this point a rectangularbrace 6; and journaled 1n the bar and the brace is a shaft 7, on whichis rnount-Y ed a band-wheel 8, a balance-wheel 9, and a crank-wheel 10,to which is attached a pitmanrod 1l. The band-wheel 8 is arranged on theshaft between the bar and the rectangular brace and within the latter.The balancewheel is arranged at one end of the shaft and at the outsideof the rectangular brace; and the crank-wheel is arranged at the otherend of the shaft, at the outer side of the horizontal bar. Theband-wheel S is grooved and receives motion from adrive-wheel12,arranged on a stub-shaft 13, which is vertically adjustable in a slot1li of the standards and a slot 15 of a bracing-plate 16, which isrectangular in form and has its ends secured to the standards. The lowerend of the pitman is adjustably secured to the crank-wheel 10 by aremovable wrist-pin 17, and perforations 18 of the crank-wheel to varythe stroke of a dasher 19. The upper end of the ptman is adjustablyconnected to a verticaily-reciprocating dasher-rod attachment 20, whichis arranged in openings of a guide 2l, and which is provided at one sidewith an arm having an eye 22, and a set-screw 23, to secure the upperend of a dasher-rod 24E, to the dasher-rod attachment. The dasher-rodattach ment 2O is approximately U-shaped and has parallel sides arrangedin openings or perforations of the upper guide 2l; and the inner arm ofthe dasher-rod attachment is extended beyond the outer one and isarranged in an opening of a lower guide 25. The upperguide 2l and thelower guide 25 are provided with threaded stems which are secured to theupper portion of the standards by nuts, and are arrangedin suitableopenings thereof. 'llhe upper ends of the standards meet and terminatein a threaded portion 26, which serves as a means for securing a braceto the standards if necessary.

The churn is simple and inexpensive in construction; is compact, andtakes up but asmall amount of space, and is capable of producing butterin a short time.

Vhat l claim is- In a churn, the combination of the standards havingdiverging lower portions, and a stra-ight solid upper portion, ahorizontal bar connecting the same neai` their lower ends, ahorizontally disposed rectangular bracing frame 6 secured to thestandards and arranged opposite the bar, a shaft 7 jou'rnaled insuitable bearings of the bar and the bracing frame, a band wheel mountedon the shaft 7 and arranged within the bracing frame, a verticallyadjustable drive wheel mounted on the standards near their upper end andconnected with the band wheel, a crank wheel arranged at one end of theshaft 7 and secured to the sanne, a balance wheel 9 arranged at theother end of the shaft, the guide 2l extending horizontally from thestandards and provided near its ends with openings, the guide 25arranged below the guide 2l and having an opening disposed directlybelow that at the inner end of the guide 21, said guides terminating attheir inner ends in threaded Shanks and passed through the solid portionof the standards and provided with nuts, an approximately U-shapeddasher rod attachment having parallel sides arranged in the openings ofsaid guides, one of its sides being longer than the other and arrangedadjacent to the standards and provided with adjusting perforations, theother side being shorter and provided with an outward extending armhaving a clamping device adapted for the attachment of a dasher rod, apitman connecting the long side of the dasher rod attachment with thecrank Wheel and having its upper end bent horizontally, and a boltpassing through the horizontally bent end of the pitman and arranged inone of the perforations of the long side of the dasher rod attachment,substantially as described.

In testimony that I claim the foregoing as my own l have hereto atlixedmy signature in the presence of two witnesses.
